The only literature published on "enhanced recovery" being implemented in the field of obstetrics was an observational study conducted with 708 C-sections at the Jessop Wing Obstetric Unit, in Sheffield, England, published in 2015. See below for the protocol used. The development of an obstetric "enhanced recovery" plan resulted from a desire for earlier discharge following cesarean section, due to pressure on national health service budgets to cut costs. There was an increase in day 1 discharges following uncomplicated cesarean sections from 1.6% to 25 % with the above mentioned protocol, and a stable 30 day readmission rate. Their conclusion was that "an enhanced recovery program was successfully implemented… Many of the interventions were straightforward and could be adopted easily elsewhere."
